Power supply for systems operating in harsh environment by means of split-core transformer

Summary

This paper describes a concept of a transformer for supplying modular power delivery systems operating in extremely harsh environment in which servicing possibility is limited. The transformer described combines functions of voltage transformation, galvanic isolation of the primary and secondary side and a power connector, whose mating does not require galvanic connection between conductive elements in harsh environment. The cable joints to the primary and to the secondary sides of the separable transformer parts can be factory-sealed hermetic elements and on-site power connection is made thanks to the separable core units. Technical challenges related with the concept presented are analyzed concluding that the transformer based on the dry type technology is feasible. The analysis is supported by experimental study on a small-scale demonstrator.
